105 Heat Index Possible Today

By National Weather Service

PADUCAH - The National Weather Service in Paducah has posted another hazardous weather outlook for today through the weekend including triple-digit heat indices for most of the region.

Afternoon heat index values will top out from 100 to 105 west of a Mount Vernon Illinois to Cadiz Kentucky line today. Over the weekend, the heat will build east, with afternoon heat index values 100 to 105 degrees across all of southeast Missouri, southern Illinois, southwest Indiana and western Kentucky.

Some locations may see readings exceed 105 degrees this weekend. A Heat Advisory may be required.

Those with outdoor activities Friday, and especially this weekend, should plan to wear lightweight and light colored clothing if possible. Take frequent breaks from the heat in the shade or preferably an air conditioned location. Remember to bring along and drink plenty of nonalcoholic beverages.
